Abstract (en)
[origin: EP2589796A1] The invention concerns a method of manufacturing a root section of a rotor blade (41) of a wind turbine. It comprises the steps of assembling (A) a plurality of supporting rods (1) with an interface section (17) to a hub interface of the wind turbine in an essentially circular shape such that there are gaps (33) between the supporting rods (1), arranging (B) first fibres (31) in the gaps (33) which first fibres (31) are physically and/or chemically compatible with an injection material, placing (C) a first molding tool (35) along an outer surface of the circular shape and a second molding tool along an inner surface of the circular shape, treating (D) the injection material so that it bonds with the first fibres (31). The invention also concerns a supporting rod holding arrangement (39) for such purpose and a root section of a rotor blade (41) manufactured by such method.
